如何订阅 angular-2-local-storage 中的 setItems$ Observable
How do I subscribe to the setItems$ Observable in angular-2-local-storage
我正在使用 angular-2-local-storage,它有一个 setItems$ 的可观察对象,我正在尝试...观察,在指令中使用以下代码:
/** app-theme.directive.ts **/
import { Directive, ElementRef, Input } from '@angular/core';
import { UserSettings } from './core/user-settings';
import { LocalStorageService } from 'angular-2-local-storage';
@Directive({
selector: '[appTheme]'
})
export class AppThemeDirective {
constructor(el: ElementRef, localStorageService: LocalStorageService) {
localStorageService.setItems$.subscribe(function(x: any) {
console.log('subscribed', x);
});
}
}
本地存储在我的代码中更新和保存得很好,但更新没有被观察到,也没有记录到控制台。我错过了任何明显的问题吗?
抱歉,一切顺利,但我需要阅读以下内容:
https://github.com/phenomnomnominal/angular-2-local-storage/issues/31 并将 notifyOptions 添加到 app.module.ts imports
LocalStorageModule.withConfig({
prefix: 'ng-starter',
storageType: 'localStorage',
notifyOptions : {setItem: true, removeItem:true}
}),
localStorage
和 sessionStorage
已经存在于 lib 中,因此您可以使用 localStorage.setItem() 和 localStorage.getItem() 直接使用它们。
mycomponent.ts
import { Directive, ElementRef, Input } from '@angular/core';
import { UserSettings } from './core/user-settings';
import { LocalStorageService } from 'angular-2-local-storage';
@Directive({
selector: '[appTheme]'
})
export class AppThemeDirective {
constructor(el: ElementRef, localStorageService: LocalStorageService) {
let data = { application: this.application };
localStorage.setItem('applicationdata', JSON.stringify(data));
var data = localStorage.getItem('applicationdata');
}
}
希望对您有所帮助。
